is a sectional view through a picker arm showing the picker spindlesmounted there on and the driving means therefor; Fig. 2 is a sideelevation of a portion of the picker arm with the picker spindlesthereon; Fig. 3 is a sectional view across the picker arm with thepicker spindles thereon; Fig. at is a sectional view through one of thecones with its picker spindle; Fig. 5 is an end view of the pickerspindle; and Fig. 6 is a sectional view of the said picker spindlesubstantially on the line 66 of Fig. 5.

In carrying out my present invention, I use a picker arm hexagonal incross section, and upon the faces of this arm the picker spindles aremounted in groups of three; that is to say, near the outer end of thepicker arm there are a series of picker spindles disposed in the sametransverse plane, but upon alternate faces of the picker arm, as shownin full lines in Fig. At a pointin rear of this first group or series ofpicker spindles there is another group of three spindles, these being inthe one plane transversely of the picker arm, and upon the faces whichalternate with the faces upon which the first series of picker spindlesis located, as shown in dotted lines in Fig. 3. Further along the pickerarm there is another series or group-of picker spindles occr pying thesame fac'esof the arm as the group mentioned above, and this order ofpicker spindles or grouping thereof is continued along the arm untilthere are six groups of three each, the said groups being arranged uponthe alternate faces of .the picker arm. The picker spindles 1 aremounted in cones 2 which, in turn, are mounted upon the shell of thepicker arm, as shown in Fig. 4. The spindles have on their inner endsgear wheels 3 which are .The picker spindles, particularly in respect oftheir engaging fingers, form an important part of my invention.

The object of this part of said invention is to facilitate the releaseof the cotton from the fingers, after it has been carried by said fingerto the proper point of discharge, and to effect such release by morereversal of rotation of the picker spindle.

In my former U. S. Patents 587201 and 796421 are shown rotating pickerspindles carrying catching points, which by the rotation. engage andhold the cotton and pull it from its place in the boll. These pointsproject in a direction approximately parallel with the axis of thespindle, and with also an outward curve, and in Patent 796421 the pointsor fingers incline also slightly forward in the direction of theengagingrotation.

In my present invention, I have had in view the easy release of thecotton from the points or fingers, simply by reversed rota tion of thespindle without. impairing the grip of the fingers upon the cotton inthe forward rotation. To this end I have so formed the fingers andarranged themupon the end of the spindle at the edge, that, in theforward rotation they will enter into and engage the cotton, while uponreverse movement, these fingers will be drawn directly out of the cottonand so absolutely release it by this reverse movement alone. I haveshown the spindle .in the form ofa tube, this being most convenient, andthe form which I preferably use. The metal of the tube being of a properthickness, the fingers may be cut out of this metal at the end of thetube. I have found two of these fingers (as shown) to be operative. Asto the form of these fingers, I refer to Figs. 4c, 5 and G of mydrawings. The fingers 8, 8,

are formed on the wall of the tube and pro-' ject in line therewith, butthe ends are bent to approximately horizontal position, and in thedirection of the forward, or engaging fingers having projectionsextending beyond cotton may be picked and cleared by simply 10 theirends in a general direction parallel rotating the fingers, substantiallyas dewith the axis of the finger and of hookscribe shape, and pointingsubstantially circumi In testimony whereof, I affix my signatureferentially, and means for rotating the fin in presence of twowitnesses.
